Chapter Summary

After reading this chapter on ammunition types, you should understand the different ammunition used in rifles, handguns and shotguns, and how to use them safely. Let's review the important points presented in this chapter:

Cartridge

  • You should know the four different parts of a cartridge and where they are located: Projectile, Casing, Powder, Primer.
 
 

Different Cartridges

  • Centerfire and rimfire cartridges primarily differ on the location of the primer. Centerfire cartridges have the primer inserted into the cartridge base whereas rimfire cartridges have the primer on the inside rim of the cartridge base.
 
 

Cartridge Firing

  • There are four steps on how a cartridge is fired. You should know these steps and be able to identify them in the correct order.
 
 

Data Stamp

  • There is a data stamp on the side of the rifle's barrel, indicating the caliber of the rifle. Always be sure to use the correct ammunition to avoid injury to yourself or damage to your firearm.
 
 

Caliber

  • Rifled barrels have spiraled lands and grooves which give the bullet a spin as it exits the muzzle, increasing accuracy. A firearm's caliber is determined by the distance between opposite lands inside the barrel.
 
 

Shell

  • A shotgun shell has five components: Case, projectile, wad column, powder, primer. Be sure you can identify these parts on a shot shell.
 
 

Smoothbore

  • Unlike rifles, shotguns used to fire shot pellets have a smoothbore barrel, meaning there is no rifling in the barrel.
 
 

Gauge

  • Shotguns are measured in gauges. Gauge is determined by the number of lead balls of size equal to the diameter of the bore required to weigh one pound. Thus, the higher the gauge, the smaller the diameter of the barrel.
 
 

Data Stamp

  • There is a data stamp on the side of the shotgun's barrel, indicating the gauge and size of ammunition to use in the shotgun. Always be sure to use the correct ammunition to avoid injury to yourself or damage to your firearm.
 
 

Chokes

  • Chokes help control the spread of the shot from a shotgun. The farther the target, the tighter the choke you need to use. Be sure to know the types of chokes available, as well as the target distances they are used for.
 
 

Slugs

  • Shotgun slugs are used in semi-rural areas since they tend to travel less far than high-power rifle cartridges. To increase a slug's accuracy, it is recommended to use a shotgun with a rifled barrel, or to use a rifled choke.
